Answer:

3.93 per hour

Step-by-step explanation:

The first 4 hours is at 20 hours / 4 hours  or 5 dollars an hours

The second  line has a slope of 2.50 dollars an hour

But there is also a surcharge when you go over 4 hours

That is a 5 dollar flat rate at 4 hours

Assuming that we do not include the flat rate in the hourly calculation

4 hours * 5 dollar + 3 hours * 2.50 = 20+7.50

27.50 is the hourly charge

Divide by 7 hours

3.928571429

3.93 per hour

I came in super late
Allushta [10]

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.


We are told to use j as the original price of the jeans, so we can set up the expression:


j-0.25j


to represent the cost of the jeans with the discount.


Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:


j(1-0.25)


j(0.75) or 0.75j


Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:


0.75j

0.75(60)=45


Therefore, the cost of the jeans after the discount is C) $45.

Find the <br> (D)<br> (R)<br> &amp;<br> (A)
omeli [17]
<h3>Answer: Choice C</h3>
  • domain = (-infinity, infinity)
  • range = (-infinity, 0)
  • horizontal asymptote is y = 0

========================================================

Explanation:

Since no division by zero errors are possible, and other domain restricting events are possible, we can plug in any x value we want. This means the domain is the set of all real numbers. Representing this in interval notation would be (-infinity, infinity).

The range is the set of negative real numbers, which when written in interval notation would be (-infinity, 0). This is because y = 5^x has a range of positive real numbers, and it flips when we negate the 5^x term. The graph of y = -5^x extends forever downward, and the upper limit is y = 0.

It never reaches y = 0 itself, so this is the horizontal asymptote. Think of it like an electric fence you can get closer to but can't touch.
